Steelmaking, as one of the strategic industries and drivers of the country's economy, faces various enviromental challenges like other industries. The electric arc furnace slag (SHF) and the dedusting dust (DD) [۱,۲] as a by-product of the factory are among the significant high-volume wastes in the steel industry. In this article, we have investigated the effect of SHF and DD wastes, from Hormozgan steel Company (H.O.S.C.O), as an additives and regulator & improver of Ph soil and Natural nitrogen fertilizer by Production and application of mineral-organic fertilizer based on zeolite on the growth and quality of )۲ Ha) garden fruit trees such as apricots, pears, apples, plums, cherries, and also crops such as wheat, barley and pumpkin in Alborz province. This was experimented mineral-organic fertilizer rates from ۳ to ۵ t/ha which an increase in growth, quality & quantitate of tree products in autumn-winter fertilization pit was observed. [۳,۴]
